Attack Tree Path: 1. Gain Unauthorized Access to Sentry Instance [HR]

  • Description: This is the overarching path to accessing the Sentry instance without proper authorization. It's the foundation for most subsequent attacks.

Attack Tree Path: 1.1 Compromise Sentry Credentials [HR] [CN]

  • Description: Obtaining valid Sentry credentials through various means.
    • 1.1.1 Phishing/Social Engineering of Sentry Admins [CN]
      • Description: Tricking Sentry administrators into revealing their credentials through deceptive emails, websites, or other communication methods.
      • Likelihood: Medium
      • Impact: High
      • Effort: Low
      • Skill Level: Novice/Intermediate
      • Detection Difficulty: Medium
    • 1.1.3 Exploit Weak/Default Sentry Credentials (if self-hosted and misconfigured) [CN]
      • Description: Using default or easily guessable passwords if the Sentry instance is self-hosted and hasn't been properly secured.
      • Likelihood: Very Low (with basic security)
      • Impact: Very High
      • Effort: Very Low
      • Skill Level: Novice
      • Detection Difficulty: Very Easy
    • 1.1.4 Leakage of Sentry Credentials (e.g., in code repositories, logs, environment variables) [CN]
      • Description: Finding Sentry credentials that have been accidentally exposed in publicly accessible locations or through insecure storage.
      • Likelihood: Low/Medium
      • Impact: Very High
      • Effort: Very Low (if found)
      • Skill Level: Novice
      • Detection Difficulty: Hard

Attack Tree Path: 1.2 Exploit Vulnerabilities in Sentry Server (Self-Hosted) [HR]

  • Description: Taking advantage of security flaws in the Sentry server software or its underlying infrastructure.
    • 1.2.1 Exploit known CVEs in Sentry or its dependencies (e.g., outdated versions) [CN]
      • Description: Using publicly known vulnerabilities (Common Vulnerabilities and Exposures) to gain access to the Sentry server.
      • Likelihood: Medium (if updates delayed)
      • Impact: High/Very High
      • Effort: Low/Medium
      • Skill Level: Intermediate
      • Detection Difficulty: Medium
    • 1.2.3 Exploit misconfigured Sentry server settings [CN]
      • Description: Leveraging improperly configured settings, such as exposed debug endpoints or weak file permissions, to gain unauthorized access.
      • Likelihood: Low/Medium
      • Impact: High/Very High
      • Effort: Low/Medium
      • Skill Level: Intermediate
      • Detection Difficulty: Medium

Attack Tree Path: 2. Manipulate Sentry Data/Configuration (After Gaining Access) [HR]

  • Description: Actions taken after gaining unauthorized access to modify Sentry's data or settings.

Attack Tree Path: 2.1 Data Exfiltration [HR] [CN]

  • Description: Stealing sensitive data captured by Sentry.
    • 2.1.2 Use Sentry's API to retrieve event data [CN]
      • Description: Utilizing the Sentry API, with compromised credentials, to extract error reports and other potentially sensitive information.
      • Likelihood: Medium (if API unrestricted)
      • Impact: High
      • Effort: Low
      • Skill Level: Intermediate
      • Detection Difficulty: Medium

Attack Tree Path: 2.3 Configuration Manipulation [HR]

  • Description: Altering Sentry's configuration to facilitate further attacks or data exfiltration.
    • 2.3.1 Change Sentry's DSN (Data Source Name) [CN]
      • Description: Modifying the DSN to redirect all future error reports to an attacker-controlled server.
      • Likelihood: Low
      • Impact: Very High
      • Effort: Low
      • Skill Level: Novice
      • Detection Difficulty: Medium
    • 2.3.2 Modify data scrubbing rules [CN]
      • Description: Disabling or weakening data scrubbing rules to prevent sensitive data from being redacted before storage.
      • Likelihood: Low
      • Impact: High
      • Effort: Low
      • Skill Level: Novice
      • Detection Difficulty: Medium

Attack Tree Path: 3. Exploit Client-Side Sentry SDK Integration

  • Description: Targeting the Sentry SDK within the application's client-side code.

Attack Tree Path: 3.1 Tamper with Sentry SDK Configuration [HR]

  • Description: Modifying the SDK configuration, typically in the client-side code.
    • 3.1.1 Modify the DSN in the client-side code [CN]
      • Description: Changing the DSN within the application's client-side code to redirect error reports to an attacker-controlled server.
      • Likelihood: Low/Medium
      • Impact: High
      • Effort: Low
      • Skill Level: Intermediate
      • Detection Difficulty: Hard

Attack Tree Path: 3.2 Exploit Vulnerabilities in Sentry SDK

  • Description: Taking advantage of security flaws in the Sentry SDK.
    • 3.2.1 Exploit known CVEs in the SDK [CN]
